Glitter-Like Iridescence within the Bacteroidetes Especially Cellulophaga spp.: Optical Properties and Correlation with Gliding Motility
Figure 3
Edges patterns of Bacteroidetes colonies.
Marine bacteria (A, B) and terrestrial bacteria (C) were grown 24 h on CYT and CY media, respectively. In (A), pictures of the entire colonies of C. lytica CECT 8139 and its mutant (impaired in gliding motility) are shown for comparison at the macroscopic level. The mutant was not iridescent on SYP, CYT, LN and sNA culture media (data not shown). All iridescent colonies exhibited typical spreading and jagged edges. Iridescent strains were: C. lytica CECT 8139 and DSM 2040 (and to a lesser extent DSM 7489), C. baltica CIP 106307, C. fucicola CIP 106308, C. pacifica LMG 21938, C. geojensis CCUG 60801, C. tyrosinoxydans DSM 21164, M. dokdonensis DSM 1720, F. johnsoniae DSM 2064, F. succinicans DSM 4002 and S. cauliformis DSM 3657.
